摘要： An improved electromagnetically actuated valve is disclosed. The improved valve design includes a layer of structurally stable, non-magnetic material, preferably Kapton or Chrome, disposed intermediate the core element and the electromagnetic element of the valve, and a core element and electromagnetic element fabricated from a high electrical resistive iron material. The layer of non-magnetic structurally stable material and high resistance core element serve to eliminate the hysteresis effect in the magnetic force of the valve. The core element may also include radially extending or axially extending perforations through the core element. The axial and radial perforations serve to reduce the weight of the core design and the axial perforations serve to reduce the effect of the air spring created in the gap as the core element approaches the electromagnetic element during operation of the valve.
